Business structure: 32% sole owners, 63% corporations, 5% LLCs; median time licensed 14.5 years.
For plumbers, underwriters focus first on: water damage from failed fittings, supply lines and water heaters; and mold claims that follow slow leaks. See the full coverage guide for plumbing contractors for limits, endorsements and workers' comp rules.
